.BALL-AND-SOCKET JOINT.

To all whpm it may concern:

Be it known that I, HARRY C. TURNER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and StateofiCalifornia, have invented new and useful &mprovements in Ball and Socket Joints, f which the following is a specifica 'on.

his invention relates toiinprovements in ball and socket joint and particularly to a joint movement having a ball and socket action.

It is an object of the invention to provide a mechanical joint for connecting members which normally extend at angles to each other, so that they may articulate properly and yet' so that there will be no lost motion or rattl -ing of the parts'with respect to each other. .1

- It is also an object of the invention to provide an adjustable ball and socket joint for mechanisms of various kinds, the ball member being so formed that it can only be inserted within the socket member in a certain way, after which it is movably confined therein.

s In the accompanying drawing formin a part of this specification, Figure 1 is a. p an view of a ball and socket joint constructed in accordance with the present invention, the dust cap thereof being shown in section. Fig. 2 is a sectional view through one member of the joint taken upon the line 22 of Fig. 1 and looking at the other member. Fig. 3 is a sectional view through the said jointtaken upon the line 3-3 of Fig. 1.

Fig. '1 is a plan view of the ball end of the ball member.

The details and features of the invention will now be more particularly described, reference being had to the said drawing in which 10 indicates the ball carrying member of the mechanical movement and 11 a socket carrying member. The said ball member 10 is formed with a ball or spherical end portion 12, which is preferably flattened upon its opposite side faces as at 13 and 14.

The socket member comprises an arm or shaft 11 having a screw threaded end portion 15, adapted to engage an interiorly threaded sleeve 16 formed with an approximately spherical socket portion 17 upon its outer end. The said socket portion is usually provided with openings at the sides, one or Specification of Letters Patent.

both of which may be formed with parallel side edges 18, whereby the opening is adapted to closely fit the transverse sectional contour of the flattened ball 12. The material of the socket extending along the side edges 18 forms a retaining means for the ball after it has been inserted in the socket and turned therein, preventing the withdrawal thereof. Any wear or slackin the fitting of the ball within said socket is takenhp by means of a plunger 19 which is usually made hollow, a spring 20 fitting at one end in the hollow portion thereof and extending at its other the arm or shaft; 11. A binding nut 22 is also mounted upon the threads of said arm or member 11 and adapted to'hold the socket sleeve 16 tightly in place upon the threaded end of said ember 11.

It will be understood that the ball member may be inserted in either. side of the open socket portion 17'and the other side of said socket portion is usually formed with an annular groove 23, when iii position adapted to receive the inwardly crimped edges 24 of a cap plate 25, which forms a grease cup. Dust and dirt are thusexcluded from the ball and socket joint within the ortion 17 and the same is at all times e ectually lubricated.

In assembling the parts the member 10 is turned so that the flattened ball'12, will enter the opening in the side of the socket member after which the said member 10 is turned or so that the flattened sides .of the ball ffiember will extend at right angles to the attened retaining edges 18 of the socket member. The member 10 is secured to any other parts to which it is to be connected be separated. The spring actuated plunger 19 prevents any looseness or rattling of the locking the same in adjusted position, the

end into a socket 21 formed in the end of' ,and the two members 10 and 11 can then not i Q s 7 mamas .bore, and. a sprmg engagmg the recessv in Withesses:
